i want to ask you, what's your sort of biggest vision of the landfill? because i pitch my artistic vision to your vision. see the thing with the big picture, it's dynamic, okay? we give it some shape and some plan, but there are new constraints that are getting imposed on us over the years... ukeles: i think the role of the artist is to be as true to your own feelings and voice that you can possibly be, wherever that takes you. what's this here? this is the bio-protection layer. what material is that? this is soil. but not as refined as this soil up here, right? well, the specifications for each soil type is slightly different. this is a little bit clearer. so, what i was looking at was the black geo-membranes, and then, the pipe will sit on top of that?
